Existing Survival Skills: James Franco will probably just help chisel away any rocks that get in the way of life or death. He might also get stuck between rocks sometimes, providing solid entertainment for the rest of the world's population.

Secret Weapon: Just give him a knife and make sure he has three stable limbs on the ground at any given time.

Secret Weapon: He will pass on the ginger gene, creating a dark army of ginger soldiers.

Existing Survival Skills: She isn't exactly a witch, but she's really good at convincing people she could cast a spell on them.

Secret Weapon: Emma will probably be the smartest person alive following the apocalypse. Future civilians will probably be able to attribute hover cars and delicious food capsules to her detailed scientific research.
